摘要
在GPS数据后期处理中,基线解算精度的高低会大大影响整个GPS数据的平差精度,如何找到一个合理的模型来尽量提高GPS基线解算精度是一个很值得探讨的问题。文中利用阳山金矿近几年采集的GPS控制测量野外数据,使用序列平均模型,采取4种方案进行基线解算数据比较,同时充分考虑卫星残差带来的影响,对序列平均模型提高精度的效果进行评估,发现序列平均模型是一个能提高GPS基线解算精度的模型,并且该模型可靠性较高。
In the GPS data post-processing,the baseline solution would greatly affect the level of precision adjustment accuracy of the GPS data.It was worth exploring the problem how to find a reasonable model to improve the accuracy of GPS baseline solution.In the paper,the author assessed the effect of sequence average model improving the accuracy using the GPS control survey field data and taking four kinds of programs to compare the baseline solution data by the sequence average model and taking full account of the impact of satellite residuals.Sequence average model could improve the accuracy of GPS baseline solution and was high reliability.
